Description
Technical field
The utility model relates to a kind of retarder system, particularly relates to a kind of carrying trailer hydrodynamic retarder system.
Background technology
Along with the fast development of Domestic Automotive Industry, the ratio that highway transportation on the way transports increases year by year, has become transportation mode on the main road of China.At resourceful mountain area and busy harbour, the transport of goods relies on heavy carrying automobile to realize substantially.Carrying trailer has the features such as rate of actual loading is high, load-carrying capacity strong, chaufeur configures less, labour cost is low, logistics cost is low, highly intensive, makes carrying trailer account for very important status in the long-distance transport of goods.Along with the increase of carrying trailer quantity in goods handling, its traffic accident occurred on highway also increases thereupon.The carrying of carrying trailer is heavy, volume is large, inertia is large, in the traffic accident that it occurs, often cause great human life and property damage.In these traffic accidents, the traffic accident caused due to the brake failure of carrying trailer accounts for significant proportion.Carrying trailer often can suffer from long descending in long-distance transport process, and chaufeur needs to step on brake pedal continually, and brake shoe brake cheek and brake wheel frequently rub, and temperature raises, and wearing and tearing increase.If brake shoe brake cheek and brake wheel often work under such circumstances, the brake system of carrying trailer is easy to produce brake failure.Friction between simple dependence brake shoe brake cheek and brake wheel can not meet the requirement of the safe reduction of speed of carrying trailer, so want carrying trailer safe reduction of speed when long descending just must adopt complemental brake system.
Utility model content
For solving the problem, the utility model provide a kind of safe, save space, carrying trailer hydrodynamic retarder system that stability is strong.
The utility model solves the technical scheme that its technical matters adopts: carrying trailer hydrodynamic retarder system, comprises maneuvering system, electronic control unit, fuel-feed system, cooling heat radiation system, hydrodynamic retarder.
Described hydrodynamic retarder, comprises pump impeller, turbine, axle drive shaft, hydrodynamic retarder housing, oil inlet, oil outlet, bearing, valve block, fixed wheel impeller, driving wheel impeller, transmission shaft, oil return line, H Exch, inflow pipeline, connects pressure air adjustment apportioning valve, pressure air, petrol storage tank.
Described oil return line one end connects pump impeller impeller, and one end connects petrol storage tank.
Be pressure air above described petrol storage tank, and be provided with above petrol storage tank connect pressure air regulate apportioning valve.
Described inflow pipeline one end connects petrol storage tank, and one end connects H Exch;
Described H Exch is connected with pump impeller impeller.
The principle of work of carrying trailer hydrodynamic retarder system: when vehicle long descending road conditions are descending sail time, pilot control control handle, the electronic control unit received signal of vehicle, Controlling solenoid valve action makes pressurized air enter petrol storage tank; Fluid is pressed in hydraulic coupler rotor chamber by petrol storage tank under air compressing effect; The epitrochoidal chamber of hydraulic coupler is filled with fluid, and the transmission shaft of hydrodynamic retarder and the pump impeller of impeller disk connect.Transmission shaft rotates outputting power, and the pump impeller of impeller disk is along with the fluid in the rotational agitation epitrochoidal chamber of transmission shaft, and under the application force of pump impeller, fluid produces centnifugal force.Centnifugal force forces fluid to get rid of to turbine by pump impeller, and turbine produces counteraction to fluid, and fluid flows out from turbine and impacts pump impeller.Such turbine just defines resisting moment to pump impeller, hinders the rotation of pump impeller, thus makes vehicle slow; Work fluid forms inlet and outlet pressure difference in motion process, and oil circulation flows, and is pulled away by heat during H Exch.
Preferably, described carrying trailer hydrodynamic retarder is arranged in trailer non-powered axle wheel nave, and described carrying trailer hydrodynamic retarder is provided with the boost installation of a set of hydrodynamic retarder.
Preferably, described boost installation adopts single-stage planetary speed increasing mechanism.
Preferably, described single-stage planetary speed increasing mechanism comprises sun wheel, gear ring, satellite gear and pinion carrier, and the center shaft of satellite gear is fixed by pinion carrier, and gear ring is with satellite gear, be all connected by meshing between satellite gear with sun wheel.
Turbine and the gear ring of hydrodynamic retarder are connected, and pump impeller and sun wheel are connected.When hydrodynamic retarder does not work, gear ring is with vehicle wheel rotation, and pinion carrier is not fixed, and sun wheel dallies on main shaft.When hydrodynamic retarder works, pinion carrier maintains static, and gear ring inputs, and sun wheel exports.Sun wheel rotating speed increases, and pump impeller is speedup along with sun wheel speedup.In working process, pinion carrier maintains static, and gear ring and sun wheel turn on the contrary, which achieves turbine reversion.Hydrodynamic retarder is designed to turbine reversion, not only can improves pump impeller and turbine relative velocity, but also the correlation parameter such as torque factor and lock torque can be improved.
The main shaft of hydrodynamic retarder is connected with the spindle nose of trailer by screw thread; Trailer wheels is connected with turbine and housing by driving fork, and they rotate with same speed; When trailer normally travels, hydrodynamic retarder does not work, and wheel drives turbine rotation, and pinion carrier is not fixed, and pump impeller dallies on main shaft, does not produce interaction force between pump impeller and turbine; When hydrodynamic retarder works, oil pump is by fluid pump people epitrochoidal chamber, and the pinion carrier of planetary speed increaser structure is fixed by power-transfer clutch, and pump impeller accelerates to rotate by speed increasing mechanism and gets rid of to turbine by fluid, produces resisting moment, stop turbine High Rotation Speed to turbine; Turbine connects with wheel antagonistic force is passed to wheel, thus realizes the slow of carrying trailer.
Preferably, described hydrodynamic retarder is located in the rim for automobile wheel of vehicle body both sides.
The beneficial effects of the utility model are: hydrodynamic retarder is arranged in the rim for automobile wheel of vehicle body both sides by (1), both can save space, can strengthen again the stability of vehicle when long downhill braking; (2).Turbine connects with wheel antagonistic force is passed to wheel, thus realizes the slow of carrying trailer.
